Original story:

At least 30 people were killed and more than 30 people injured in a bomb blast inside a hospital in Pakistan’s Quetta city in Balochistan province on Monday.

The blast took place as soon as a group of lawyers arrived at Quetta’s Civil Hospital in support of their colleague who was shot earlier in the day.

At least 50 people had entered the hospital’s emergency department accompanying the body of slain lawyer and president of Balochistan Bar Association, Bilal Anwar Kasi.

Balochistan Home Secretary Akbar Harifal said, “The blast occurred after a number of lawyers and some journalists had gathered at the hospital following the death of the president of the Balochistan Bar Association in a separate shooting incident early this morning.”

Police reportedly said that after the blast, unidentified men opened fire. Pakistan’s Frontier Corps and the police have arrived at the scene and the area has been cordoned off. An emergency was declared in all hospitals across the city.

Journalists were also injured in the blast. A cameraman for DawnNews was severely injured and another cameraman Shahzad Khan who was with Aaj TV was killed.
